The planning date for the launch debut of SpaceX’s Crew Dragon spacecraft has been pushed to no earlier than (NET) March 2019 per sources familiar with the matter, potentially creating a direct schedule conflict with the company’s planned operational debut of Falcon Heavy, also NET March 2019.

At the same time as delays to the Commercial Crew Program continue to increase the odds that NASA will lose assured access to the International Space Station (ISS) in 2020, both of SpaceX’s critical missions are entirely dependent upon the support of its Kennedy Space Center-located Launch Complex 39A (Pad 39A), creating a logistical puzzle that will likely delay Falcon Heavy’s second launch until Crew Dragon is safely in orbit.

As of the first week of December 2018, SpaceX was reportedly planning towards a mid-January 2019 launch debut for Crew Dragon. By the end of December, DM-1 was no earlier than the end of January. By the end of January, DM-1 had slipped to from late-February to NET March 2019. Put in slightly different terms, SpaceX’s Crew Dragon launch debut has been more or less indefinitely postponed for the last two months, with planning dates being pushed back at roughly the same pace as the passage of time (i.e. a day’s delay every day).

Admittedly, DM’s apparently indefinite postponement may well be – and probably is – more of an artifact than a sign of any monolithic cause. While the US government’s longest-ever shutdown (35 days) undoubtedly delayed a major proportion of mission-critical work having to do with extensive NASA reviews of SpaceX and Crew Dragon’s launch readiness (known as Readiness Reviews), much of the 60+ day DM-1 delay can probably be attributed to the complexity of the tasks at hand. Being as it is the first time SpaceX has ever attempted a launch directly related to human spaceflight, as well as the first time NASA has been back at the helm (more or less) of US astronaut launch endeavors in more than 7.5 years, significant delays should come as no surprise regardless of how disappointing they may be.

The most consequential aspect of DM-1’s two-month (at least) delay will likely be the myriad ways it feeds into delays of SpaceX’s in-flight abort (IFA) test and first crewed launch (DM-2), and thus’s NASA’s ability to once again independently launch US astronauts. Given that SpaceX’s DM-2 is expected to occur around six months after DM-1 and that the final certification of Crew Dragon for official astronaut launches will likely take another 2-3 months, these delays – barring heroics or program modifications – are pushing NASA dangerously close to the edge of losing assured US access to the International Space Station (ISS).

According to a July 2018 report, the Government Accountability Office (GAO) analyzed the Commercial Crew Program and NASA’s human spaceflight program more generally and concluded that NASA would lose assured access to the ISS in November 2019 if Boeing and SpaceX continued to suffer delays and were unable to reach certification status by then. This comes as a result of NASA’s reliance on Russian Soyuz launches for access both to and from the ISS, launch and return service contracts which have no replacements (aside from SpaceX and Boeing). While GAO noted that NASA could likely delay that loss of assured access until January 2020, even that might be pushing it if SpaceX’s DM-1 delay continues much further.

“[While NASA is working on potential solutions, it] has not yet developed a contingency plan to address the potential gaps that [future delays in Boeing and SpaceX schedules] could have on U.S. access to the ISS after 2019.” – GAO, July 2018

Prior to DM-1’s delay from NET January to NET March 2019, SpaceX was targeting an In-Flight Abort test roughly three months after DM-1 (it will reuse DM-1’s Crew Dragon capsule), DM-2 six months after DM-1 (NET June 2019), and NASA certification and the first operational astronaut launch (PCM-1) as few as two months after DM-2 (August 2019). It’s reasonable to assume that delays to DM-1 will impact subsequent Crew Dragon launches roughly 1:1, as DM-2 and its many associated reviews hinge directly on DM-1, while the same relationship also exists between PCM-1 and DM-2. As a result, Crew Dragon’s two-month delay probably means that SpaceX’s NASA certification will occur no earlier than October 2019, giving NASA no more than 90 days of buffer before the US presence on the ISS drops from around 50% (3 astronauts) to 0%.

Crew Dragon and Falcon Heavy walk into a bar…

The unexpected delays to Crew Dragon’s DM-1 launch debut are likely placing SpaceX in an awkward situation with respect to the operational launch debut of Falcon Heavy, meant to place the terminally delayed Arabsat 6A satellite into orbit no earlier than March 7th, 2019 (at the absolute earliest). DM-1 is also targeting a launch sometime in March, posing a significant problem: both Falcon Heavy and Crew Dragon can only launch from Pad 39A, while the on-site hangar simply doesn’t have the space to support schedule-critical Falcon Heavy prelaunch work (mainly booster integration and a static fire test) and no less critical Crew Dragon launch preparations simultaneously.

 

Much like SpaceX’s inaugural Falcon Heavy rocket spent a month and a half fully integrated and more than two weeks in a static-fire limbo (albeit due to one-of-a-kind circumstances) before its launch debut, SpaceX’s second Falcon Heavy rocket – comprised of three new Block 5 boosters and Heavy-specific hardware upgrades – is likely to take a good deal more time than a normal Falcon 9 for prelaunch processing. Almost all of that Heavy-specific testing depends on the rocket being integrated (i.e. all three boosters attached) for preflight fit and systems checks and a wet dress rehearsal (WDR) and/or static fire ignition test.

It’s entirely possible that SpaceX integration technicians are able to complete the process of swapping out Crew Dragon and Falcon 9, modifying the transport/erector (T/E), completing Falcon Heavy booster integration, and installing Falcon Heavy on the T/E quickly enough to allow for simultaneous DM-1 and Arabsat 6A processing. It’s also possible that an extremely elegant but risky alternative strategy could solve the logistical puzzle – as an example, SpaceX could roll Crew Dragon and Falcon 9 out to Pad 39A a week or more before launch to give Falcon Heavy enough space for full integration, whereby Falcon 9’s necessarily successful launch would clear the T/E and allow it to be rolled back into 39A’s hangar for Falcon Heavy installation.

The most likely (and least risky) end result, however, is an indefinite delay for Falcon Heavy Flight 2, pending the successful launch of Crew Dragon. This is very much an instance where “wait and see” is the only route to solid answers, so wait and see we shall.

Starlink is ‘biggest competitive advantage,’ but it’s temporary, United CEO says

Published

United Airlines CEO Scott Kirby said that SpaceX’s Starlink satellite internet is its leading competitive advantage in the U.S. airline industry. However, in recent comments, while he described the service as “the biggest competitive advantage” the carrier currently holds, he also acknowledged that the edge is temporary.

“…everybody eventually is going to have high-speed low earth orbit internet connectivity. It’s going to be a must-have. We are going to have a few years of being the only airline that has it at scale, and that’s our mission,” Kirby said. Until everyone has it, United aims to capitalize on its head start by converting trial users into long-term loyal customers.

United has moved faster than its rivals on Starlink installations. As of mid-to-late October 2026, the system was on roughly 43 percent of its fleet, with plans to reach 61 percent by year-end, 87 percent by June 2027, and full fleet coverage by the end of next year.

The airline already operates more Starlink-equipped flights than the rest of the U.S. industry combined. Los Angeles International Airport is scheduled to become United’s first 100 percent Starlink hub in the first half of 2027, and the carrier’s app will display the likelihood that any given flight has the service.

Kirby has pointed to early evidence that the offering influences booking decisions. Some passengers loyal to other airlines are already switching flights for Starlink connectivity, something the airline, along with American Airlines, has tried to leverage against competing airlines. Both companies used status-match programs, and some of those customers are pursuing company-specific credit cards, which signals an intent to stay.

Once onboard, these customers encounter the airline’s broader investments in aircraft, larger seat-back screens, oversized bins, connection tools, and a mobile app that Kirby says outperforms competitors. Wi-Fi satisfaction scores on Starlink-equipped planes have been reported to be nearly double those on aircraft with other systems.

Competitors are moving slowly to do the same. Southwest Airlines began installations in 2025 and expects to complete them soon. Delta is pursuing Amazon’s Leo system, while American expects to start Starlink work in early 2027 and has not yet detailed regional-fleet plans. This timeline gap gives United a multi-year window in which it remains the only major U.S. carrier offering Starlink at scale.

Kirby has framed the strategy as pressing that advantage while simultaneously widening gaps in other technology areas so that customers who try United for the Wi-Fi remain for the overall experience.

The approach reflects a calculated bet that superior in-flight connectivity can accelerate share gains and support longer-term financial targets, including a 10 percent pre-tax margin goal.

High-speed internet is particularly valued by premium and business travelers who can work or stream reliably. As low-Earth-orbit service becomes ubiquitous, the temporary nature of the pure connectivity edge means United’s retention will depend on whether its other product and operational improvements keep pace.

How SpaceX Is raising Raptor’s sea-level thrust while holding engine mass steady

Published

SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.

Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.

This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.

This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.

Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.

Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.

The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.

Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.

For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.

Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.

Tesla expands Robotaxi geofence in Houston with an ode to SpaceX merger

Published

on

Tesla expanded its Robotaxi geofence in Houston, Texas, today, enlarging the service area and drawing a new rocket-shaped boundary across the city’s northwestern and central parts.

Although CEO Elon Musk said it was just a coincidence, the expansion seems to be an ode to SpaceX and its potential merger with Tesla.

The official Tesla Robotaxi account announced the change with the lines “Houston, we have liftoff” and “Bigger service area now live,” pairing them with a map overlay.

The prior white geofence, roughly 25 square miles covering Jersey Village, Harvest Bend, and the Willowbrook corridor along U.S. 290 and State Highway 249, now sits inside a larger blue zone that stretches southeast toward Bellair and closer to central Houston.

Houston’s Robotaxi service launched on April 18, 2026, the same day as Dallas, as Tesla’s first unsupervised public expansion beyond Austin. From the start, the vehicles were Model Ys running without anyone in the front seats, booked through the dedicated Tesla Robotaxi app and open to the public inside the geofence.

Trackers measured the initial zone at about 25 square miles; by late September it had not grown substantially. Community and registry data indicated a modest local fleet of unsupervised Model Ys, while dozens to nearly 200 Cybercabs, the purpose-built, steering-wheel-free two-seaters, have been spotted staging and testing in Houston lots, though public Cybercab rides remain limited to Austin for now.

Across the broader Robotaxi program, Tesla began public Robotaxi rides in Austin in June 2025, as a small geofence and vehicles with safety monitors became available for a ride-hailing service. Later on, Tesla removed the monitors and steadily expanded the service area until it covered most of the Austin metro area.

Unsupervised Robotaxi services now run in six cities: Austin, Dallas, Houston, Miami, Orlando, and Tampa. Cumulative driverless miles reported by the company have reached several million. The Cybercab entered public service in Austin in early September 2026 and has scaled rapidly there. The company has also said that Dallas is next for Cybercab rides in November, with further cities and 24/7 hours targeted by year-end, plus fleet-operator sales of the vehicle.

Waymo also operates a fully driverless service in Houston, which has been open to the public since August of this year.

The Houston expansion continues Tesla’s pattern of starting with tightly controlled validation zones before widening coverage as real-world data accumulates, while the rocket motif on the map underscores the company’s habit of injecting visual flair into its autonomy rollout.

Riders inside the new boundary can request unsupervised Model Y trips in the Robotaxi app; exact operating hours and further Cybercab availability remain subject to app updates and company statements.
